Hello,
I'm trying to use raspberry pi to program nRF52832 on mass production. Because it's easy to do some test job with raspberry pi.
But there are still some issue I have no idea how to resolve them.
Env:
-
Raspberry Pi 3B+ (Software up-to-date)
-
OpenOCD (compile from github repo)
-
nRF52832 (Custom dev board, works fine with keil and SES on windows)
I tested the OpenOCD with programming a STM32 board, it works fine. So I think that it may not be the OpenOCD's issue.
When I'm trying programming nRF52832, the stdio printed these lines:
pi@raspberrypi:~/openocd_test/test $ sudo openocd -f nrf52test.cfg Open On-Chip Debugger 0.10.0+dev-00908-g9879f9bf (2019-06-13-13:35) Licensed under GNU GPL v2 For bug reports, read http://openocd.org/doc/doxygen/bugs.html Info : BCM2835 GPIO JTAG/SWD bitbang driver Info : SWD only mode enabled (specify tck, tms, tdi and tdo gpios to add JTAG mode) Info : clock speed 1001 kHz Info : SWD DPIDR 0x2ba01477 Info : nrf52.cpu: hardware has 6 breakpoints, 4 watchpoints Info : Listening on port 3333 for gdb connections target halted due to debug-request, current mode: Thread xPSR: 0x01000000 pc: 0xfffffffe msp: 0xfffffffc Info : nRF52832-QFAA(build code: E0) 512kB Flash target halted due to debug-request, current mode: Thread xPSR: 0x01000000 pc: 0xfffffffe msp: 0xfffffffc target halted due to debug-request, current mode: Thread xPSR: 0x01000000 pc: 0xfffffffe msp: 0xfffffffc ** Programming Started ** Info : Padding image section 0 at 0x00000964 with 1692 bytes Info : Padding image section 1 at 0x0001e7c0 with 2112 bytes Info : Flash write discontinued at 0x00033c5c, next section at 0x00078000 Info : SWD DPIDR 0x2ba01477 Error: Failed to read memory at 0x4001e400 Error: Couldn't read NVMC_READY register Error: Failed to erase reg: 0x4001e508 val: 0x00006000 Error: failed erasing sectors 0 to 51 embedded:startup.tcl:449: Error: ** Programming Failed ** in procedure 'script' at file "embedded:startup.tcl", line 26 in procedure 'program' called at file "nrf52test.cfg", line 13 in procedure 'program_error' called at file "embedded:startup.tcl", line 508 at file "embedded:startup.tcl", line 449
The content of nrf52test.cfg shows below:
source ./raspi3.cfg transport select swd set WORKAREASIZE 0x2000 source [find target/nrf52.cfg] init reset halt nrf5 mass_erase reset halt program ./firmware.hex verify reset exit reset run exit
And the config file raspi3.cfg:
interface bcm2835gpio bcm2835gpio_peripheral_base 0x3F000000 # Transition delay calculation: SPEED_COEFF/khz - SPEED_OFFSET # These depend on system clock, calibrated for stock 700MHz # bcm2835gpio_speed SPEED_COEFF SPEED_OFFSET bcm2835gpio_speed_coeffs 146203 36 # Each of the SWD lines need a gpio number set: swclk swdio bcm2835gpio_swd_nums 25 24
Because I have tested programming STM32 board, so the connection problems could be exclude.
And I have tried to use `set WORKAREASIZE 0` instead of `0x2000`, it didn't work.
